Answer:
President Woodrow Wilson, on 8th of January, 1918 presented the 14 Points proposal to end World War I and to forestall a similar occurrence in the future.
Explanation:
The war was fuelled by ambitions of the then central powers to take over empires and grow their influence and power. Prior to the war, there had been a series of complicated agreements between them which led to the war when the agreements failed to hold.
US not being party to any of these agreements finally stepped in to stop the war and to call parties involved to make public their war objectives since every war must have one.
When they didn't due to the nature of such ambitions, Woodrow Wilson presented the 14 Points Proposal which in summary called for nations to abide by moral principles as a basis for their foreign policies and relations.
